This article describes the purpose and setting of tiny switches found inside of some room thermostats. These little slide or toggle switches may control the heating system on-off cycle rate or burner-on time in a manner similar to the heat anticipator feature found in other room thermostats. Here we describe various types of internal or "hidden" switches found in some wall thermostats and in a table form we summarize their proper setting.
In most cases you can safely install a new room thermostat without worrying about these switches - just leave the switch or switches in the factory-set position. But in some circumstances setting the switches correctly may involve a change .

At HEAT ANTICIPATOR Operation we explained that on some room thermostats internal switches are used to control the heating system on-off cycling rate, sensitivity, or fan functions in a manner that provides benefits similar to the heat anticipator found on other room thermostat devices. Here we describe various types of internal or "hidden" switches found in some wall thermostats and in a table form we summarize their proper setting. In most cases you can safely install a new room thermostat without worrying about these switches - just leave the switch or switches in the factory-set position. But in some circumstances setting the switches correctly may involve a change .
At THERMOSTAT INSTALLATION STEPS we provide a step by step photo guide to installing a room thermostat.
